Description
- A mass in the scrotum or testicle can be noted by the patient or during a routine exam.
- Lesions can be in the scrotal wall, testicle, or paratesticular tissues.
- Testicular masses can usually be distinguished from other common intrascrotal masses (hydrocele, varicocele, spermatocele, epididymal cyst, hernia) based on exam or imaging studies.
- Most palpable testicular tumors in adults are malignant; 80% nonpalpable lesions are benign.
- Children with testicular tumors are more likely to have benign lesions (20–40% benign).
Epidemiology
Depends upon the diagnosis:
- Varicocele: 15–20 % adult males
- Hydrocele: 6% of full-term infants
- Paratesticular tumors: <10% of intrascrotal tumors
- Testicular cancer: Most common solid tumor in men between 18 and 40
Risk Factors
- Malignancy: Cryptorchidism, prior testicular neoplasm or hematopoietic ...
